Midcoast Energy Partners, L.P. (NYSE: MEP) ("MEP") announced today that the board of directors of its general partner declared a quarterly cash distribution of $0.3575 per unit on all of its outstanding common and subordinated units, for the quarter ended December 31, 2016. The approved distribution remains unchanged from the previous quarter. The distribution is payable on February 14, 2017, to unitholders of record at the close of business on February 7, 2017. Upon the payment of the distribution for the quarter ended December 31, 2016, it is anticipated that the subordination period with respect to MEP subordinated units owned by Enbridge Energy Partners, L.P. ("EEP") will end and the subordinated units will convert into common units on a one-for-one basis.

Merger Agreement

MEP also announced that it has entered into a definitive merger agreement with Enbridge Energy Company, Inc. ("EECI"), an indirect subsidiary of Enbridge Inc. (NYSE: ENB), whereby EECI will acquire, for cash, all of the outstanding publicly held common units of MEP at a price of US$8.00 per common unit for an aggregate transaction value of US$170.2 million. The transaction price represents a 5.5 percent premium to the trailing 30 trading-day volume weighted average price of MEP common units as of January 26, 2017.

The transaction is expected to close in the second quarter of 2017. Upon closing, MEP will cease to be a publicly traded partnership. The transaction will be a taxable event to MEP's unaffiliated unitholders with recognition of gain or loss in the same manner as if they had sold their MEP units for the transaction price. The transaction is the result of the strategic alternatives review process, announced on May 2, 2016.

A committee of independent directors of the board of directors of the general partner of MEP (the "MEP Conflicts Committee") was formed on December 5, 2016, to review, evaluate, consider and negotiate the terms of the merger agreement. The MEP Conflicts Committee, after consultation with its independent legal and financial advisors, approved the merger agreement and determined that the merger agreement and the transactions contemplated by the merger agreement are fair and reasonable to and in the best interests of MEP and its unaffiliated unitholders. Among other things, the MEP Conflicts Committee took into consideration MEP's projected financial performance and the implications on MEP's financial position, existing credit agreement covenants and distribution coverage, and any potential actions to address such matters, as reflected in the projected financial and operating data reviewed by the MEP Conflicts Committee. The board of directors of the general partner of MEP, acting based in part upon the recommendation of the MEP Conflicts Committee, unanimously approved the merger agreement and determined that the merger agreement and the transactions contemplated by the merger agreement are fair and reasonable to and in the best interests of MEP and the limited partners. The closing of the transaction is subject to certain closing conditions, including the approval of the holders of a majority of the outstanding common units of MEP.

Upon the conversion of the subordinated units owned by EEP described above, EEP will own approximately 52 percent of MEP's then outstanding common units. In connection with the execution of the merger agreement, MEP has entered into a support agreement with EECI and EEP whereby EEP has agreed, in its capacity as a holder of MEP units, to vote its units in favor of the merger agreement and the transactions contemplated by the merger agreement.
